The pleural sandwich sign in two cases of primary pleural lymphoma.

Kim Y, Lee M, Ryu YJ, Cho MS - Korean J Radiol (2015)

Bottom Line: The sandwich sign is used to describe mesenteric lymphoma in which mesenteric vessels and fat are enveloped by enlarged mesenteric lymph nodes.We present two cases of primary pleural lymphoma demonstrating the "pleural sandwich sign".Histopathological examinations confirmed low grade marginal zone B-cell lymphoma in an 80-year-old man and diffuse large B-cell lymphoma in a 68-year-old man.

ABSTRACT
The sandwich sign is used to describe mesenteric lymphoma in which mesenteric vessels and fat are enveloped by enlarged mesenteric lymph nodes. We present two cases of primary pleural lymphoma demonstrating the "pleural sandwich sign". Contrast-enhanced computed tomography showed conglomerated parietal pleural and extrapleural masses encasing the intercostal arteries. Histopathological examinations confirmed low grade marginal zone B-cell lymphoma in an 80-year-old man and diffuse large B-cell lymphoma in a 68-year-old man. The pleural sandwich sign may suggest the diagnosis of primary pleural lymphoma.

Sandwich sign in 68-year-old man with primary pleural lymphoma (diffuse large B-cell lymphoma).A. Axial image of contrast-enhanced CT showing right pleural effusion and diffuse pleural mass extending into extrapleural space and paraspinal region. Sandwiching of intercostal artery by conglomerated pleural and extrapleural masses is noted by arrows. B. Pleural fluid cell block specimen showing numerous large atypical lymphoid cells (hematoxylin and eosin stain, × 400 magnification).

Mentions: A 68-year-old man was admitted due to dyspnea for 2 weeks. He had no medical history. His laboratory findings were normal. Testing for HIV virus was not performed. Chest radiography showed right pleural effusion. CT revealed right pleural effusion with a diffuse pleural mass and a few small lymph nodes in the mediastinum and left axilla. The pleural mass was homogeneous. It invaded into the extrapleural space with encasement of the intercostal arteries, demonstrating a sandwich sign (Fig. 2A). On FDG-PET, hypermetabolism was noted in the pleural mass.
